If you have old CDs, or scrap ones due to buffer underruns or while burning it, here's a suggestion. Take an air rifle target and tape it on the CD. Centre it precisely.

Now go and shoot. Through the centre hole, of course. Without damaging the CD, of course. For many shots, of course.

The hole in the centre is 15 mm. Effectively, for air rifle 10m this means that you have to shoot better than 8.9. Easy, ain't it?

Gave it a try myself for the first time this evening. It felt pretty much like match pressure...

For even more pressure use Your favorite brand new CD that you just paid $22.95 for.

Geweldig! (Great!)
I have a lot of LP gramaphone records in a box on the attic.
What do I have to shoot to keep them in 1 piece?

The thought crossed my mind. As long as I'm shooting around 560, I should stick with the garbage CDs...

As for Albert's suggestion:
vinyl records have a 0.7 cm diameter hole. A score of 10.5 or higher and your precious audio memories are still OK.

Vinyl singles have a 3.8 cm diameter hole. Easy: an air rifle score of 4.3 or better is sufficient. This one's perhaps more useful for air pistol, of for smallbore rifle @ 50 m.
